AI video generator longer than 30 seconds
Short answer on finding an AI video generator longer than 30 seconds: there is not one. No model on the market generates more than about 16 seconds in a single pass today, and anyone promising a 30-second generation is either stitching clips for you or describing a roadmap.
That is worth saying plainly, because most pages targeting this question avoid it. Below is the real maximum length of every video model on SoonMaker, read straight from the model registry, and the workflow people actually use to reach 30 seconds and beyond.

How people actually get past 30 seconds
You generate several clips and join them. That is what every "long AI video" tool is doing underneath, whether or not it tells you.
The part that decides whether the result looks like one video or like three clips glued together is consistency: the same character, the same lighting, the same style across every clip. Models with reference-image support hold a subject steady far better than models that only take a text prompt, which is why the reference-driven models matter more than raw clip length.
A practical sequence: generate the longest clip your chosen model allows, take the final frame, use it as the starting frame of the next clip, and repeat. Continuity comes from the handover frame rather than from the prompt.
Which models to chain
Models that accept a starting frame or reference images chain more cleanly than text-only ones.
| Model | Maker | What it is for |
|---|---|---|
| Veo 3.1 | Google's highest-quality video model with cinematic output and automatic audio generation. | |
| Kling 3.0 | Kuaishou | Kuaishou's latest video model with fast generation, camera motion control, and start/end frame support. |
| Seedance 2.0 | ByteDance | Frontier video that holds subject and style across the shot using multiple reference images. |
| Hailuo 2.3 | MiniMax | MiniMax's frontier model, known for strong, high-energy movement. |
| Vidu Q3 | Vidu | The video model tuned for anime and stylised animation, not just photoreal footage. |
| LTX-2 | Lightricks | Fast, inexpensive video with native sound, from an open model by Lightricks. |
| Grok Imagine | xAI | xAI's video model: quick, high-quality clips with sound at a very low cost. |
| PixVerse v6 | PixVerse | Fast video generation with sharp movement and effects that respect physics. |
| HappyHorse 1.1 | HappyHorse | Generates video with matched sound and lip movement from text, references, or a source video. |
| Veo 3.1 Lite | The lowest-cost Veo 3.1 tier, audio still included. | |
| Veo 3.1 Fast | The faster, more affordable Veo 3.1 — still with native audio. | |
| Kling 2.6 | Kuaishou | High-quality Kling video with native sound, without the flagship price tag. |
| Wan 3.0 | Alibaba | Text, first-frame and first+last-frame video with native audio, from Alibaba Wanxiang. |
| Seedance 2.0 Fast | ByteDance | ByteDance’s Seedance 2.0 in a faster, lower-cost variant. |
| Hailuo 2.3 Fast | MiniMax | The quicker, cheaper Hailuo — MiniMax's high-dynamic motion at roughly half the price. |
36 models are available on one account — 18 for images and 18 for video.
Questions
- Is there an AI video generator longer than 30 seconds?
- Not as a single generation. The longest single clip available here is 16 seconds. Longer videos are produced by generating multiple clips and joining them.
- Why are AI videos so short?
- Cost and coherence. Generation cost scales with length, and quality degrades the further a model has to extrapolate, so providers cap the length rather than ship footage that falls apart at the end.
- Which model gives the longest clip?
- Vidu Q3 at 16 seconds, with several models at 15. The duration table above is generated from the live registry, so it stays accurate as models change.
- Does a longer clip cost more?
- Yes, roughly proportionally. Credit costs are quoted per 5 seconds and scale with duration.
